Dynamic hydraulic or pneumatic seals are generally referred to
as automatic seals since they do not need to be adjusted once they have been
installed. It is therefore important to install packing sets correctly to get
optimum, performance. It is essential when installing the Vee packing not to be
over compress the set. The set should be allowed sufficient loading to initially
seal but yet flex or relax on a stroke return.

Removing old packing.

A.) Use extreme care in removing the
old packing, avoid any damage to the associated metal parts.

B.) After removal of the packing set, the sealing space must be
thoroughly cleaned. Caution should be exercised to prevent damage to metal
components, Particularly when removing compacted or solidified deposits from
metal surfaces. Be extremely careful to flush any of the debris out of the
system. Any contaminants remaining in the system will shorten seal life.

C.) Examine metal components. Scratches and gouges that are not repaired
at this stage will result in substantially reduced sealed life.

II. Installation:

A.) Cleanliness must be maintained throughout the procedure.

B.) Protect the seals from nicks and cuts. Damage is
commonly caused by passing the seal over sharp edges, shoulders, ports or
threads during installation. Such obstructions should be masked or shielded
to prevent damage.

C.) Lubrication greatly eases his installation and
equipment reassembly. Satisfactory results are often obtained by using the
system fluid as the lubricant.

D.) When installing V-rings, make sure that they are facing in the
direction of the media of being sealed, whether liquid or air. This ensures
that the system pressure will energize the seal lips and set them for proper
sealing.

E.) Seat each ring individually making sure that sections of the rings
are not turned over or twisted.
